WINDOW-CLEANING v DEVICE'.

I lappiication mea 'August ai, i922.` seriai No. 585,576.

Be it known that we, SAM MirzEN- MACHER, Sr., and SAM MrrznNMAoHER,-Jr.,` citizens of the United States, and residents of the citv 'of Chicago, county of Cook, and

VState of'llinois, have invented certain new s and useful lmproveinents 1n Window-Glean ing Devices, of which specification,

' Qur invention relates to :a window-cleanv ing device an'd has for its object to provide means for washing the outside of a window as well as the insideY thereof whileY standing'- `on the insideofa room and window,

*Other objectswill appear hereinafter.

, The invention 'consists in the combinations; v f and arrangements of l scribed andclaimed.

parts hereinafter de- The invention will beibest understood .byl

`reference tolthe accompanying drawings forming-a part of-this specification, and in which- Y j f Fignl isan 'elevational view of thepreferred `form ofour invention;

' Y view thereof taken on line 2-2 of Fig.1;

rj Fig. 3 shows a modified form of our inevention, viewed on line 3-,3 of Fig. 4;

vrFig;` 4 is an enlarged vertical sectional:

'of our invention.k Y

Fig..` 2 isan enlarged' vertical sectional view taken on line 4.-4 of: Fig. '3, and- Fig. 5 is .a view 'of another Y The form ofour invention illustrated in Vto said cleaning means.

Figs. l and 2 comprises a-cylindrical housing 10 provided with a .bracket 11 Vwhich is arranged to Y,embrace the upper sash rail 12 of a window .13, for mounting the housingv on either'the outside or the inside of a'window, whichever side is to be cleaned. A coiled spring 14Khas oneend fastened in the.

upper part of'saidl housing, and a lcleaningmember or means 15 is attached to the other Vend of said spring, as by means `of diverging arms 16 releasably connected lwith one end to said spring and with the other end A bracket '17iS mountedon the outer part of said housing and beneath the same for guiding saidY spring and preventing it and the attached cleaning means 15 from moving or swingin outward or from the window.

he cleaning member 15 preferably comprises a brush or body member with means in the form of bristles 18 on oneside for washing the window, and with means in the form of a rubber'strip 19 fastened to said the following is a modified lformv manual pull on saidcable.

member 15, on the side opposite the bristles, for removing the moisture lfrom the windowl and for drying ,it.- 'A- receptacle o r liquidV container 2O is placed at the bottom'v oftheV window forreceivingand moisteniiig. the bristles or washing meanslS. VAny suitable washingrmeans and drying means may be substituted for Vthe bristles and thel rubber striprespectively, and the liquid container or dispenser mayV4 consist kof any suitable device and may be arranged in' any-suitable v.A flexible. member or cable 21 isprovidedYY `for manually operating the device, and is' Vpreferably fastened v.to thercleaning 'member, as by meansfof a hookj22 which en- .gagesdetachably inthe eyepof. a screw 23 fastened to said member 15, f

Thefdevice is conveniently passed from the room through thefwindow, rabovethe lowered upper sash, `and thebracket 11 is` Y readily clamped onto the upper rail ofi the window sash, while the frame .'10V .extends outward along the window frame, if th'e'outso Sd/Qf thetWndOW iS t0' be Cleaned, andthe i' Cleamng means engages :the Outer' Sdeo ff;

the window pane. The descending cable 21 may be manually engaged and drawn.down

ward through thel slightly lraised lower winv dow, thereby placing thespring under-tensioii, which spring.l thereafter moves said Y cleaning means upward :upon ceasing of the `Figs- 3 kandl 4 illustrate i a"modified -ormY lofoperating mechanism, whichrrcomprises, a housing 30 provided with Ja bracketlf for embracing thesasli rail'12.v `fheli'cal spring 32` has lits inner end held adjustably in position` in said housing'by meanslof a shaft f3?, to whichitis fastened` and `which ariatcliet 34 and nawl: fThe` shaft 33 is heldv` against rotation in said housingby e cleaning means-against the window. -Tlie divergingarms 16 of the cleaning ymeans 15 as describedV in the preferred form; Y.

In Fig. 5, a further modified VforinA ofY operating Vmeans vis shown, which comfree end of thespring. is attached to the,A V

prises .a leaf spring 40 fastened with onel v vpreviously described.

The manner of mounting and operating each of the modii'ied forms is substantially the same as described in regard to the preerred form. y

:While We have illustrated and described the preferred form `of construction for carrying our invention into effect, this is capable of variation and modification .Without 'departing from the spirit of the ,in-

vention. -We, therefore, do not Wish to be limited to the precise details of construction set liorth, but desire to avail Vourselves of such variations 'and modiiications as come Within the scope of the appended claims.

Having described our invention, `what We claim asneiv and desire to secure by Letters Patent is:
